Application led March B. 1918. Serial No. 221.103.

To all whom it may concern:

. Be it known that I, NORMAN C. Nicol., a

- citizen of the United States of America, and

a resident of the city of Buffalo, county of Erie, and State of NewYork, have invented certain new and useful improvements in Hinges, ofwhich the following is a full, clear, and exact description.

My invention relates generally to hinges and more particularly to hingesof the concealed type, and which may be used on doors, gates, windowsash, piano covers, wardrobes, closets, and for various kinds of cabinetwork.

The principal object of my invention has been to provide a hinge whichshall be simple in its operation and very compact in its design, so thatit may be attached to comparatively thin materials.

Another object has been lto provide a hinge, the construction and oeration of which is such as to prevent t e movable member, to which itis attached, when in its closed position, froml moving away from thestationary trame or support to which it is pivotally attached. t

A further object has been to provide a device which shall have such aradius of movement as to give the movable member the desired amount ofthrow, whereby rubbing of the parts is prevented during the operation ofthe hinge, and whereby the same is made adapt-able for differentthicknesses of material.

The above objects and advantages have been accomplished bythe deviceshown in the accompanying drawings. In the drawings:

Figure 1 is a front view its open position.

Fig. 2 is a sectional elevation of my device and is taken on line 2-2 ofF1 1, with the hinge members in their close position.

Fig. 3 is a front elevation of my hinge, showing the relation of partswhen the same is partially closed. y

Fig. 4 is a sectional elevation taken on line 4-4 of Fig. 2, showing theinner face of one of the hinge leaves.

Fig. 5 is a transverse sectional elevation taken on line 5-5 of Fig. 1.

Fig. 6 is a front elevation of a modified form of hinge.

Fig. 7 is a longitudinal, sectional elevation of another modified formof hinge.

of my hinge in I Referring now to the drawings, and partlcularly toFigs. 1 to 5, inclusive, 10 are the casings 0f my hinge, which arepreferably made of sheet metal and formed in the shape of a box, asshown. 11 may represent the stationary member and 12 the mov- -ablemember, to which my hinge is attached;

the casings being 1ct into the edges of these members and set in flushwith the face thereof. The usual screws 13 serve to retain the casingsin position.

The butts are connected by a supplemental hlnge comprising leaves 15 and16. flhese loaves are pivotally united at their inner ends 17 'by a pin18, Whose axis lies midway between 'the casin s, when in their openposition and paralle to the faces of the side walls thereof. The end 17of preferablv the leaf 15' is provided with a lip 19 which contacts withthe upper surface of the end 17 of the leaf 16 when the parts are intheir open position, as shown in Fig. .5, so that the ends are preventedfrom opening through an angle greater than 180. By th1s arrangement, theleaves close readily and binding thereof is prevented. The outer end ofeach of thc leaves 15 and 16 is pivotally united with one of the casings10 by means of a pivot pin 20. These pins are opposltely arranged, each.at an angle of 45o to the face of either of the side walls of thecasings and they are supported within the casings 10 by means of a *lug21, formed preferably by bending a portion of the end wall of thecasing, and by an indented portion 22, formed preferably from one of theside walls of each of the casings. The

outer ends of each of the leaves is provided with a tab 23 and a tab 24,which are bent at substantially right angles to the face of the leavesand are pivotally attached to the pivot pins 20.

It will be seen, by reference to Fig. 2, that the two leaves 15 and 16do not fully .close when the hinge is in its closed posiin Figs. 2 and4f.A In order to make the leaves 15 and 16 of light material and yet ofsucient strength, the edges are preferably bent up at right angles tothe face of the leaf, as clearly shown in the drawings. Each of thecasings is provided with a closure plate 25, which is pivoted within thecasing at the end opposite the pivotal connection ofthe leaves and whichis arranged to close the openings within the casings when the hinge isin its open position, as lshown in Fig. 1. These plates are mounted uponpivot pins 26 and are elevated to the position shown in Fig. 1, by meansof a sflxring 33, arranged beneath each plate. The p ates are maintainedin the position shown in Fig.v 1, by any suitable means, but prefeifablya tab 27, formed from the side wall of the casing and bent over at rightangles so as to act as a stop for the outward movenient of the plate.

In Fig. 6, I show a modification of my hinge, where the outer ends ofthe leaves 2 8 are pivotally united-to the casings 29 at angles ofsubstantially 30 withwthe side wall of either of the casings 29.` AOneof the leaves 28"is shown in its closed position by the dotted lines inthe left hand casing of Fig. 6. This View shows that, the pivot pins atthe outer ends of the hinge leaves need not necessarily be arranged atan angle of 45 with the side walls of the c asings, but that this anglemay be made 30 or varied to any other suitable angle. v v -I In Fig. 7where I show another modified form of my invention, all the 'pivotalpins have their axes arranged in parallel planes. Thus the pivotal pins"3 1 for the, outer ends of the leaves are arranged parallel to eachother when completely closed or open and each always parallel to thecentral pivotal From the foregoin 1t will be seen that my hinge is'verycompact in its design and requires the use of a comparatively few parts,thus making itvery durable and not liable to get out of order. As shownin Fig. 3, my hinge when opening separates the parts to which it isattached, so that they have `reached 'nearly the maximum separa-- tionwhen opened to an angle of 90. Morerover the connections of all theparts in myhingeyare pivotal, thus doing away with all .slidingconnections and the resulting friction.

From the' foregoing, will be seen that the leaves of the supplementalhinge are so1 mounted that when the casings are moved toward or fromeach other, the central pivot of lthe supplemental hinge leaves willmove through a plane which is at right angles with the plane of rotationof the casings and assume constantly different angular relations withthe casings.

While I have shown and described. the leaves of my supplemental hinge ashaving an angular connection with the casings of substantially 45 and30, it is obviousfthat the parts may have any desired angular re,-lation.` plate 25 may be omitted, and the pivot pins tion o f myinvention, it is preferably advisable, 1n order to secure the requiredstabil ity, to use more thanA one supplemental hinge. v

It will be clearly understood, however, from the foregoing descriptionthat when a plurality of supplemental hinges is employed, it will be aduplication of the single structure .herein shown and described. Theseand other 'modifications of the 'details herein shown and described maybe made without departing from the spirit of my invention or thescope`of the appended. claims, and I do not, therefore, wish to belimited to the exact embodiment herein shown andA de- Furthermore, ifdesired, the closure f for the inner ends of the leaves may be ar-`ranged in parallel planes or in planesat an angle to each other. Owingto the construc-4 ico ings, a two-leaf supplemental hinge pro-` videdwith a central pivot, a pivot pinfor the outer end of each leaf of thesupplemental hinge, each pin being mounted in the casings and angularlyarranged with respect to the faces of the side walls of the casings, andmeans for preventing the supplemental hinge members from opening throughan angle greater than 180. 3.
